python - Handling missing packages or DLLs in a PyQt app -

-

What is a good way to handle fatal errors - missing packages, .ui files are not compiled, QT DLL or shared object Have not met, etc. - in PyQt app (or other python app)?

Displaying a cross-platform message box without the QT DLL or shared objects looks a lot like a dumping message in the console does not seem very useful, because the end user will not see the console. How do other python applications handle it? Or do they believe that properly installed app will not run into these problems?

Distilts model operates correctly installing a python application, or a third party setuptools Package is also easy for end users.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
